Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic auxiliary equipment, and particularly relates to an eye drop auxiliary device. Background Technique

[0002] With the changes in people's lifestyles and working conditions, the time of using eyes is increasing. For example, looking at computers, playing mobile phones, watching TV, playing video games for a long time, etc., it is very easy to suffer from visual fatigue and dry eye. Sometimes in the hospital, it is necessary to drip eye drops into the eyes of patients. However, when patients drip eye drops, generally, one hand is used to hold the eyelids open by themselves or by medical staff, and the other hand is used to squeeze the eye drop bottle, so that the eye drops in the eye drop bottle drip into the eyes. However, holding the eyelids open by hand will cause pollution to the eyes. Therefore, some eye drop auxiliary tools have appeared. By searching for existing publicly disclosed patents, it is found that the eye drop auxiliary tools can be roughly divided into two categories. The first category is designed based on glasses, and the second category is designed based on clips (or brackets) for holding the eyelids open. The second category of auxiliary tools can force the eyelids to open when dripping eye drops, making it more convenient to drip medicine.

[0003] For example, the Chinese patent with the publication number CN215131466U discloses an eye drop auxiliary device, which includes a substrate. On both sides of the substrate, a group of mounting plates are symmetrically installed. The number of each group of mounting plates is two. On the two mounting plates in the same group, a rotating shaft is inserted and rotatably connected. On each rotating shaft, a dial is fixedly installed. On each dial, a connecting plate is fixedly installed. A silica gel sleeve is sleeved on the connecting plate. The above utility model effectively prevents the situation that the bacteria on the fingers infect the patient's eyes due to the separation of the eyelids by using fingers, increases the safety of the eyes when dripping eye drops, and prevents the situation that the patient closes the eyes by himself due to fear when dripping eye drops, causing the medicine to drip on the eyelids. This prior publicly disclosed patent belongs to the second category of the above-mentioned auxiliary tools, and there are also the following deficiencies: the two dials are driven by torsion springs to open, and then used to hold the eyelids open. However, the elastic force of the torsion spring is certain, and the opening process is not controlled by people. Therefore, it is difficult to be suitable for different patients and different eye conditions, and there is a problem of poor applicability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an eye drop auxiliary device to solve the problems put forward in the above background technique.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an eye drop auxiliary device, comprising a lever arm, an eye medicine bottle and a support seat, the support seat is a rectangular block structure, the lever arm is provided with two and is respectively hingedly installed on two opposite sides of the support seat, the middle part of the support seat is provided with a through hole penetrating up and down, the head of the eye medicine bottle passes through the through hole and is clamped with it, the lower end of the lever arm is fixedly connected with an arc-shaped eye-supporting plate, and symmetrical connecting plates are fixedly connected with teeth at the ends of the connecting plates, and the teeth of the two connecting plates are meshed with each other, and two fixed shafts are respectively provided on the symmetrical sides of the support seat, the fixed shaft passes through the connecting plates at corresponding positions and is rotatably connected thereto, the fixed shaft is connected to the connecting plates at corresponding positions by a torsion spring, the upper part of the lever arm is hinged with a fan-shaped dial button, and the lever arm is provided with a rectangular hole, and the dial button can be flipped toward the surface of the lever arm and pass through the rectangular hole.

[0006] Preferably, the upper end of the lever arm is provided with a bent portion bent outward, and the bent portion is used to prevent the pinching finger from detaching from the upper end of the lever arm.

[0007] Preferably, a screw is threaded onto the inner side of the dial button, and its extension length can be adjusted by turning the screw.

[0008] Compared with the prior art, the utility model has the following beneficial effects: when in use, the thumb and index finger are used to slowly press the upper end of the lever arm, so that the two eye-opening plates are opened and the eyelids are opened. The opening size can be freely controlled by the person according to different patient conditions. The two lever arms are synchronously linked, so the opening process can be controlled more smoothly, and the remaining fingers are used to push the lever button to control the squeezing of medicine. The squeezing action and the eye-opening action are independently controlled and completed by one hand, which is flexible and convenient to operate and has good applicability.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0013] Embodiment 1

[0014] See alsoFigure 1-2 , the present utility model provides a technical solution: a device for assisting in dropping eye drops, including a dial arm 1, an eye drop bottle 2, and a support base 6. The support base 6 is in the structure of a rectangular block. There are two dial arms 1, which are respectively hinged and installed on the opposite sides of the support base 6. The two dial arms 1 form a clip structure. A through hole penetrating up and down is provided in the middle of the support base 6, and a soft sleeve adapted thereto is embedded and installed in the through hole. After the head of the eye drop bottle 2 is inserted into the soft sleeve, clamping can be achieved. An arc-shaped eye-opening plate 3 is fixedly connected to the lower end of the dial arm 1. The eye-opening plate 3 is made of silica gel material to increase the friction with the skin. An outwardly curved bending portion 9 is provided at the upper end of the dial arm 1. The bending portion 9 is used to prevent the pinching finger from detaching from the upper end of the dial arm 1. When in use, a posture of grasping upright with the hand can be adopted, and then the upper part of the dial arm 1 is pinched with the index finger and thumb.

[0015] Symmetric connecting plates 4 are fixedly connected to both sides of the middle of the dial arm 1. Tooth teeth are provided at the ends of the connecting plates 4. The tooth teeth of the two connecting plates 4 mesh with each other. Two fixed shafts are respectively provided on the symmetric sides of the support base 6. The fixed shafts penetrate through the corresponding connecting plates 4 and are rotatably connected thereto. Thus, the two dial arms 1 can achieve synchronous and opposite flipping. The fixed shaft and the corresponding connecting plate 4 are connected by a torsion spring 5. The torsion spring 5 is used to drive the lower ends of the two dial arms 1 to approach each other. A fan-shaped dial button 7 is hinged to the upper part of the dial arm 1. A rectangular hole 10 is provided on the dial arm 1. When the dial button 7 flips towards the surface of the dial arm 1, it can penetrate through the rectangular hole 10. A screw 8 is screwed inside the dial button 7. By screwing the screw 8, its protruding length can be adjusted. By pushing the dial button 7 towards the eye drop bottle 2 with a finger, the outer end of the screw 8 can contact the eye drop bottle 2 for extrusion.

[0016] Working principle: When in use, the eye-opening plates 3 are respectively abutted against the upper and lower sides of the eyes, and then the upper ends of the dial arms 1 are slowly pinched with the thumb and index finger, so that the two eye-opening plates 3 move away from each other to open the eyelids. The opening size can be controlled according to the conditions of different patients. Since the two dial arms 1 are synchronously linked, the opening process can be controlled relatively smoothly. After opening the eyelids, one of the remaining three fingers is used to push the dial button 7 (pushing one of the dial buttons 7 is enough) towards the eye drop bottle 2, so that the nut part of the screw 8 contacts and squeezes one side wall of the eye drop bottle 2, and the eye drops are squeezed out and dropped into the eyes. The operation can be completed with one hand.

[0017] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
